DISK WHEEL Filed Sept. 2, 1 925 INVENTOR DORSAY M CALL WHITE ATTORNEY Patented June 28, '1932 UNITED STATES PATENT OFFICE nonsay moan, warm, or CHICAGO, ILLINOIS, Assiexon, BY xnsivn assremmnrs, I s 'ro nnmnx BRAKE comrm, or cmcaeo, rumors, a conronarroxg or rumors v 1 max WHEEL Application filed September 2, 1925. Serial m. 54,050.

This invention relates to wheels, and is illustrated as embodied in a front automobile disk wheel. An object of the inventionis to lessen the cost of a wheel of this character E by forming the wheel disk and the brake drum, and preferably also the hub, all in one piece. In the illustrated form, the hub is drawn outwardly of the disk and the brake drum inwardly, suitable seats for anti-fric- 16 tion bearings being provided in the ends of the hub.

In one desirable arrangement the wheel disk continues radially from the inner edge of the brake drum and is turned outwardly as a rim-supporting flan e. The annular depression between this ange and the brake drum may, if desired, be covered by a light,

annular stampin I Various novel eatures of construction, and the great advantage of the invention, will be apparent from the following description of. one illustrative embodiment shown inthe ac-- companying drawing, in which:

The figure is a vertical section through the through associated parts.

The novel wheel shown includes awheel disk 10, drawn outwardly at its center to form an integral tubular hub 12. This hub is preferably bored out from opposite ends to form cylindrical seats 14 for anti-friction bearings (not shown) between the hub and the spindle 16 of a front wheel knuckle 18.

At the ends of seats 14 nearest the center of the hub are formed abrupt bearing positioning shoulders 20. A cap 22 may close the end of the hub.

Some distance further from its center than hub 12, the wheel disk is drawn in the opposite direction to form an integral cylindrical brake drum 24, shown closed by a backing plate 26 carried by knuckle 18, it being intended that the friction means of the brake disk inside of drum 24.

Wheel disk 10 continues radially from the inner edge of the brake drum, preferably flaring outwardly, and is turned outwardly at able tire-carrying demountable rim 30. The

top half of a front automobile wheel, and

be housed between plate 26 and the wheel its edge to form a flange 28 supporting a suitannular depression 32 between flan e 28 and drum 24 may,'if desired, be covered y a light annular stamping 34 having an opening affordlng access to the tire valve 36 projectin into the depression throughopenin 38 and 40 inrim 30 and in the wheel dis While one illustrative embodiment has been described in detail, it is not my mtention toxlimit' the sggpe of the invention to that particular em iment, or otherwise than by the terms of the appended claims.

I claim 1. A one-piece wheel disk and brake drum having an integral tubular hub projecting outwardly at its center, and formed with an inwardly-projecting brake drum further from its center, the disk continuin radially from the inner edge of the brake drum and terminating in an outwardly-directed rimsup orting substantially cylindrical flan e, sai flange and drum defining an outward y opening annular depression, in combination with a relatively light annular stamping covergig said annular depression.

2. drawn outwardly at its center forming a hub portion and outwardly at its margin formmg a rim supportingl flange portion and inwardly between said ub andmarginal flange forming a brake drum portion, and a rim mounted on said rim supporting flan e ortion in 'such position that its centra p ane bisects said brake drum portion.

3. .A wheel having a supporting tubular central hub portion and outwardly at its margin forming a'cylindrical rim supporting flange portion lying substantially between radial planes drawn throu h the ends of the hub portion and drawn. in t e opposite directioILout of the line of said flange and hub portions forming a cylindrical ,"brake drum portion, and a rim mounted on said rim supportingv flange portion in such position that its central plane bisects said brake drum portion. Y

4. A wheel comprising a brake drum, a closure wall integral therewith, a. wheel web integral with the brake drum, said wheelweb adapted to carry a tire retaining means on wheel having assu'pporting disk disk drawn outwardly at its center forming a.

the eri hery thereof; the wheel com a si gle piece structure pressed or ibrm from sheet metal, said combination drum and web acting jointly to sustain the vehicle load 5 imposed thereon, and said tire retaining means .center and brake drum center being in the same plane to evenly and centrally apply the brake retarding force to the tire. 5. A vehicle wheel comprising a one-piece 10 'wheel disk having an inwardly projecting brake drum midway between its edge an center, an integral" tubular hub projecting outwardly at its center, and an outwardly directed flange at its outer edge, and a' tirecarrying rim supported on said flange, the parts being so arranged that the central planes of said rim and brake drum substantially coincide.

In testimony whereof I have hereunto 20 signed my name. I
